低产油井计量现状及发展趋势

Current Situation and Growth Tendency of Low Producing Well Metering

低产油井产液量波动大、产出液中含水率呈无规律性变化、油气产量均较低等,这些因素给及时准确计量低产油井的产量、含水率、产液量等均增加了难度。容积式计量法、重量计量法、油水两相分离密度法、车载式综合油井计量装置、示功图法计量法等用于低产油井计量,各有优缺点。高精度、快速化、自动化是低产油井计量的发展方向。

Low producing wells, with large fluctuation of produced fluid content, irregular change of produced water -cut and low oil and gas productivity, make it more difficult to meter the production, water-cut and fluid production of low producing wells accurately and timely. Volume metering, weight metering, density metering hy separating oil from gas, mobile integrated well metering and indicator diagram metering have advantages and disadvantages respectively. High accuracy, rapidness and automation are the growth trends of low producing well metering.
